Japanese Patent JP7380385
Kind Code:
B2
Abstract:
To reduce a position deviation of a work-piece (a coil conductor) caused by an injection pressure at an injection molding.SOLUTION: The present invention discloses a manufacturing method of a stator (21), includes: a step of preparing a plurality of coil conductors (22a) in which both end parts extended to an outside of a slot (2111) of a stator core (211) are bonded; a mold closing step of performing a mold closing of a first molding and a second molding in a state where an end part (400) bonded to the plurality of coil conductors is positioned in a molding space (30) formed by the first molding (70 and 140) and the second molding (80 and 150); and an injection molding step of forming a molding part (60 and 60A) of a molding material at each end part by transmitting the molding material welded in the molding space in a state where the mold closing of the first molding and the second molding is performed in the mold closing step. The mold closing step contains a step of pressing the plurality of coil conductors in a mold closing direction by the first and second moldings.SELECTED DRAWING: Figure 4C
